Stroboscope DSL-300

Measuring range 30 - 300000 flashes per minute (FPM)
Frequency range 0.5 - 5000 Hz

LED-hand held stroboscope for non-contact determination of revolutions, for monitoring moving parts and ascertain the oscillation frequency of running systems

Industrial stroboscope for battery operation with LCD display

Stroboscope with shock-proofed aluminium housing and 7 LED illuminants

CE mark

Special Features

Stroboscope DSL-300 with easy to read LCD display

7 LED illuminants assure a good illumination of the observing object

1500 Lux at a distance of 20 cm and 6000 FPM

Double-flash-function (x 2) and half-rate-flash function (: 2) for easy and fast determination of the true flash rate

Adjustable flash duration time for best illumination
– e. g. shorter flash period = tighter image
– e. g. longer flash period = more brightening

Adjustable delay time of internal trigger signal and flash for optimal monitoring of motion sequences

Protection class IP65 (splash water and dust protection)

Battery operated

Additional function: Stroboscope DSL-300-T with trigger input and output

External trigger signal
– Adjustable delay time in milliseconds (ms) between external trigger input signal and flash for optimal monitoring e. g. clock frequency or starting period of a machine
– Phase shift between trigger signal and flash to make a rotating part visible in different degrees
– Pulse divider to determine which input pulse should be used as signal for the flash

Standard Features

Selectable units Hz, rpm or FPM

One hand use

Handy, shock protected housing

Calibration report of manufacturers optional available
